Isaiah mows a lawn in 3 hours. what unit fraction would be used to convert this to the number of minutes it takes him to mow a lawn?

60 minutes/ hour = 60/1

60/1 x 3 = 180 minutes

  9.5 ft wide by 24 ft long

Step-by-step explanation:

A graphing calculator shows there are two solutions to the system of equations ...

  2x + y = 43 . . . . . . fence length when x= width

  xy = 228 . . . . . . .  area

The solutions are ...

  (width, length) = (9.5, 24)   or   (12, 19)

Since we want the length as long as possible, the choice of dimensions is ...

  length = 24 feet; width = 9.5 feet.
